In the crystal structure of the title compound, C14H12ClNO2S, the molecules display a trans conformation with respect to the C=N double bond. The dihedral angle between the methylsulfonyl benzene and chlorobenzene rings is 59.59 (8)°. The crystal packing is stabilized by weak C-HO interactions and by - stacking interactions between inversion-related methylsulfonyl benzene rings [centroid-centroid distance = 3.8579 (11) Å].
